丢了少年失了心丢了少女失了情
[diū le shăo nián shī le xīn diū le shăo nǚ shī le qíng]
It can be translated as 'Lost the youth, lost the heart, lost the girl, lost the love'. Conveys multiple levels of loss—the carefree days of youth, emotional turmoil, romantic failure—and a sense of being unable to find one's way back to those simpler times.
